Summary:

The National Longitudinal Study of Adolescent Health (Add Health) is a longitudinal study of a nationally representative sample of adolescents in grades 7-12 in the United States during the 1994-1995 school year. The Add Health cohort has been followed into young adulthood with four in-home interviews, the most recent in 2008, when the sample was aged 24-32. The additional files contained in this component of the Add Health project are from the Adolescent Health and Academic Achievement (AHAA) study and provide an opportunity to examine the effects of education on adolescent behavior, academic achievement, and cognitive and psychosocial development in the 1990s. The AHAA study contributes to Add Health by providing the high school transcripts of Add Health Wave III sample members. The AHAA data provides indicators of (1) educational achievement, (2) course taking patterns, (3) curricular exposure, and (4) educational contexts within and between schools, all of which can be linked to the Add Health survey data.

Methodology

Study Purpose:
The Adolescent Health and Academic Achievement (AHAA) study provides an opportunity to examine the effects of education on adolescent behavior, academic achievement, and cognitive and psychosocial development in the 1990s.

Sample:
Wave I, Stage 1 School sample: stratified, random sample of all
high schools in the United States. A school was eligible for the sample if it
included an 11th grade and had a minimum enrollment of 30 students. A feeder
school, a school that sent graduates to the high school and that included a 7th
grade, was also recruited from the community. Wave I, Stage 2: An in-home
sample of 20,745 adolescents consisting of a core sample from each
community plus selected special oversamples was interviewed in 1995. Eligibility for the oversamples was
determined by the adolescent's responses on the In-School Questionnaire.
Adolescents could qualify for more than one sample. At Wave II, respondents who were in grades 7-11 at Wave I were re-interviewed. Wave III: The in-home Wave
III sample consists of Wave I respondents who could be located and
re-interviewed six years later. Wave III also collected High School Transcript
Release Forms to be used for the AHAA study. At Wave IV, 15,701 Wave I respondents were re-interviewed in 2008.

Time Method:
Longitudinal: Cohort/ Event-based

Mode of Data Collection:
record abstracts

Data Source:

High school course transcripts

Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:

Performed consistency checks.

Standardized missing values.

Checked for undocumented or out-of-range codes.

Restrictions

These data are enclave-only and may only be accessed at ICPSR's location in Ann Arbor, MI. Users wishing to view these data must first contact DSDR, complete a Restricted Data Use Agreement (available as part of the documentation for this study), and receive permission to analyze the files before traveling to Ann Arbor.
